FORCE-FEED Fo'a nAavEs'rEn-HEAnnias.

Specification of Letters Patent,

Patented Feb. 20, 1917.

Application filed July 28, 1915. Serial No. 42,395.

My present invention pertains to har-.

Yester headers; and it contemplates the provision of a force-feed designed and adapted for use at the mouth of a header and constructed with a view to facilitating the passage of bushy or tangled grain into and through the header spout.

The invention in all of its details will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a detail front elevation illus-' trating my novel force-feed mechanism as properly arranged relative to the cutting apparatus and header of a harvester.

Fig. 2 is a plan of the'same. v

Fig. 3 is an'elevation showing the side of the header and feed mechanism opposite to that shown in Fig. 1.

Fig. 4 is a view taken at a right angle to Fig. l and from a view point at the left of said figure. I

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The header spout 1 may be and preferably is of the ordinary construction with the exception that its side walls are provided with extensions in which are arcuate slots 11.

The lower endless carrier 3 and the upper endless carrier 5 of the header are also of the usual type; the lower carrier beingarranged on a roller 2 and the upper carrier on a roller 4. The endless carrier 6, in rear of the cutting apparatus, indicated by 6 in Fig. 1, is of the conventional construction. The said cutting apparatus 6 is also of the ordinary or any other suitable construction.

The shaft 7 of the roller 4 is driven in the conventional manner or in any other approved manner from a working part of the harvester, and on said shaft 7 are pivoted the side plates 8 of my novel mechanism. At intermediate points said plates 8 have long, lateral bearings 8 and these are disposed in the areuate slots 11 in the side plates of the spout 1 so that adjustment 1?. 0., raising or lowering of the outer end of the spout will not change the position of the force-feed mechanism relative to the mouth of the spout. In common with header spouts of the ordinary well-known construc- Fig. 3, with a shoe 50 which is slipped over a cap 51 of the platform roller 52 of the header comprised in the harvester, the frame of which is numbered 53. The weight of the spout, as usual, holds it in position, and the bearing of the shoe 50 constitutes a pivotal connection of the header spout 1 with the frame of the harvester. The shoe 50 is carried bya bracket 54 which is fixedly connected with the lower end of the spout 1, as indicated by 55.- v 1 For the purpose of adjusting the forcefeed mechanism vertically and adjustably fixing the same to meet difierent conditions, I employ the mechanism shown in Figs. 1 and 4. Said mechanism comprises a movable arm 24 pivotally connected to and designed to be adjustably fixed with respect to the harvester frame, Fig. 4, and a bail 22, connected at 23 with the arm 24, and also connected at its ends with plates 8.

plates 8 and also equipped with a sprocket gear 18, arranged outside the spout 1, Fig. 3, bearing boxes 16 adjustable on the plates 8 in the direction of the length thereof, a sprocket gear 17 fixed on the shaft 7, Fig. 3, a sprocket belt 19 connecting the gears 17 and 18, a belt-tightener 20 equipped with a shoe 21, a shaft 12 journaled in the boxes 16 and equipped with sprocket wheels 13, sprocket belts 14 mounted on the sprocket wheels 10 and 13, and transverse slats 15 connected with and carried by the belts 14. The belt tightener 20 is in the form of a curvilinear spring that is fixed atone end to the spout 1, Fig. 3, and is so. arranged that it tends to move its shoe 21upwardly against the upper stretch of the belt 19, thereby maintaining the belt at all times in a taut state and assuring a positive drive of the force-feed shaft 9 from the carrier shaft 7.

As shown at 22 in Fig. 2, the roller 4 is preferably provided with end flanges, designed and adapted to keep the carrier or tion, the spout 1 is provided at its lower end,

sprocket wheels 10, disposed between the-- draper 5 free from the side plates or frame of the force-feed mechanism.

In practice when the grain delivered to the mouth of the header spout is of a bushy character or is in a tangled state, the lower stretch of the endless carrier comprised in. the force-feed serves to positively move such grain into the mouth of the spent and this in a regular and even manner so that choking of the mouth of the spout or any interference with the regular movement of the grain up the spout between the opposed stretches of the carriers or drapers 3 and 5 is precluded.

It will be gathered from the foregoing that my novel force-feed mechanism is readily applicable to any type of harvester that embodies an upper and lower carrier or draper to elevate grain of any kind.

I have entered into a detailed description I of the construction embraced in the present and preferred embodiment of my invention in order to impart a full, clear and exact understanding of said embodiment. It is to be understood, however, that I do not limit myself to the specific construction and relative arrangement of parts, as in the future practice of my invention such changes in construction may be made as do not involve departure from the scope of my claims.

When desired the bail 22 is disengaged from the hook 23 to enable the force feed to swing downwardly to a lower position, as conditions necessitate,

Having described my invention, what I claim and desire to secure by Letters Patent, is: I

1. A harvester comprising a frame, a header spout pivotally connected with said frame and arranged to be swung vertically; said spout having side plates in which are arcuate slots, upper and lower endless carriers in said spout, an endless carrier constructed and arranged to deliver grain to the mouth of the header spout, vertically-disposed side plates pivotally connected with the spout and arranged between the side plates thereof and having long lateral bearlngs dlsposed in the arcuate slots of said Copies of this patent may be obtained for side plates, an endless carrier mounted in the second-named side plates and having transverse slats, lower and upper shafts complementary to said endless carrier, the lower shaft being journaled in said lateral bearings, a driving connection intermediate one of the endless carriers of the header spout and said lower shaft, a vertically-mow able arm adjustably fixed to the harvester frame and overhanging the second-named side plates, and means connecting said side plates with said arm.

2. A harvester comprising a frame, cutting apparatus, a header spout pivotally connected with said frame, upper and lower endless carriers in said spout, an endless carrier arranged in rear of the cutting apparatus of the harvester and disposed in a plane below that .of the space between the lower portions of the carriers in the spout, a suitably-supported endless carrier arranged above the carrier in rear of the cutting upparatus and pivotally connected with and extending upwardly and inwardly from the mouth of the spent, and meansfor driving said carriers.

3. A harvester comprising a frame, cut ting apparatus, a header spout pivotally connected with said frame, upper and lower endless carriers in said spout, an endless carrier arranged in rear of the cutting ap paratus of the harvester and disposed in a plane below that of the space between the lower portions of the carriers in the spout, an endless carrier arranged above the carrier in rear of the cutting apparatus and pivotallyrconnected with and extending upwardly and inwardly from the mouth of the spout, a vertically-movable arm adjustably fixed to the harvester frame and overhanging the last-named endless carrier, and means connecting said carrier with said arm.

In testimony whereof I have hereunto set my hand, in presence of two subscribing witnesses.
